我有以下代码来解析country选择自动完成列表的时间:
$('#spot_address').autocomplete({
// This bit uses the geocoder to fetch address values
source: function(request, response) {
geocoder.geocode( {'address': request.term }, function(results, status) {
// Get address_components
for (var i = 0; i < results[0].address_components.length; i++)
{
var addr = results[0].address_components[i];
var getCountry;
if (addr.types[0] == 'country')
getCountry = addr.long_name;
}
response($.map(results, function(item) {
return {
label: item.formatted_address,
value: item.formatted_address,
latitude: item.geometry.location.lat(),
longitude: item.geometry.location.lng(),
country: getCountry
}
}));
})
},
// This bit is executed upon selection of an …我正在使用Rails 2.3.8.我的代码:
<%= f.radio_button :status, "draft" %>
<%= f.label :status, "Draft" %>
<%= f.radio_button :status, "published" %>
<%= f.label :status, "Published" %>
输出:
<input id="shop_status_draft" name="shop[status]" type="radio" value="draft" />
<label for="shop_status">Draft</label>
<input checked="checked" id="shop_status_published" name="shop[status]" type="radio" value="published" />
<label for="shop_status">Published</label>
显然,label没有正确地关联我的单选按钮.我想label和单选按钮一样id.我怎么能纠正这个？
谢谢.
升级Rails 3.2.到Rails 4.我有以下范围:
# Rails 3.2
scope :by_post_status, lambda { |post_status| where("post_status = ?", post_status) }
scope :published, by_post_status("public")
scope :draft, by_post_status("draft")
# Rails 4.1.0
scope :by_post_status, -> (post_status) { where('post_status = ?', post_status) }
但我无法找到如何做第2和第3行.如何从第一个范围创建另一个范围？
对于以下代码:
<span class="map-marker" data-lng="101.7113506794"></span>
<span class="map-marker" data-lng="101.6311097146"></span>
var abc = $('.map-marker:first');
var xyz = abc.getAttribute("data-lat");
console.log(xyz);
我收到错误消息:TypeError: abc.getAttribute is not a function.我做错了什么？
我自己做的就是:前端和后端.我精通HTML和CSS,但是Ruby on Rails中的菜鸟.既然我想开发这个网站,我想知道我是应该从前端开始还是从后端开始.我现在为前端做的事情都是静态的.当我做后端时,我担心我必须改变很多前端编码.
只是想知道,我们何时应该使用private或protected模型中的某些方法？
有时候,我不能没有在打扰我的组的方法private,也没有protected.我只是保持原样.但我知道这一定是一种不好的做法,否则这两个分组将不会在编程中创建.
谢谢.
不确定这是否可行.我认为Twitter Bootstrap标题大小太大了.h1是36px; h2是30px,依此类推.
有没有办法按比例减少标题大小？假设我只想要每个标题的90%.我不想逐个声明每个标题的字体大小.
谢谢.
使用Rails.我有以下代码:
class TypeOfBlock < ActiveRecord::Base
has_and_belongs_to_many :patients
end
class Patient < ActiveRecord::Base
has_and_belongs_to_many :type_of_blocks, dependent: :destroy
end
使用这些表格:
????????????????
?type_of_blocks?
????????????????
? id ? name ?
????????????????
? 1 ? UP ?
? 2 ? LL ?
? 3 ? T ?
????????????????
?????????????????????????????????
? patients_type_of_blocks ?
?????????????????????????????????
? type_of_block_id ? patient_id ?
?????????????????????????????????
? 1 ? 1 ?
? 1 ? 2 ?
? 2 ? 2 ?
? 3 ? 3 ?
? 2 ? 4 ?
? …在database.yml,reconnectRails 3和4 的默认设置是false.什么是共同的设置,在什么情况下我们应该设置它true？谢谢.
